DOM Manipulation
JavaScript can change any part of a webpage in real time.
JavaScript
Tap for example →
document.querySelector('h1')
  .textContent = 'Changed!';
document.body.style
  .background = '#000';
JavaScript Example
📡
APIs & Fetch
APIs let your code talk to other services. Fetch gets data from the internet.
JavaScript
Tap for example →
fetch('https://api.example.com')
  .then(res => res.json())
  .then(data => console.log(data));
JavaScript Example
🗂️
Arrays & Objects
Arrays store lists; objects store structured data.
JavaScript
Tap for example →
const user = {
  name: 'Alex',
  scores: [95, 87, 92]
};
JavaScript Example
🎭
Events
Events fire when users interact — click, type, hover.
JavaScript
Tap for example →
btn.addEventListener('click',
  (e) => {
    console.log('Clicked!');
  });
JavaScript Example
🔄
Async & Promises
Some things take time. Async/await makes it readable.
JavaScript
Tap for example →
async function loadData() {
  const res = await fetch(url);
  const data = await res.json();
  return data;
}
JavaScript Example
🐍
Python Lists & Dicts
Python's most powerful data structures.
Python
Tap for example →
scores = {'Alice': 95, 'Bob': 87}
for name, score in
  scores.items():
  print(f'{name}: {score}')
